实现代码如下：

// 定义车类 class Car { private String name; // 车名 private int rent; // 租金 private int capacity; // 容量

// 构造函数
public Car(String name, int rent, int capacity) {

    this.rent = rent;
    this.capacity = capacity;
}

// 获取车名
public String getName() {
    return name;
}

// 获取租金
public int getRent() {
    return rent;
}

// 获取容量
public int getCapacity() {
    return capacity;
}

}

// 客车类 class PassengerCar extends Car { private int passenger; // 载人数

// 构造函数
public PassengerCar(String name, int rent, int capacity, int passenger) {

}

// 获取载人数

    return passenger;
}

}

// 货车类 class GoodsCar extends Car { private int cargo; // 载货量

// 构造函数

}

// 皮卡类 class Pickup extends Car { private int passenger; // 载人数 private int cargo; // 载货量

// 构造函数
